Science experiments and home remedies, a cooking staple and a sour smell. Today we’re talking about and celebrating one of the mysteries of the kitchen that seems as at home under the sink as it does in the pantry: Vinegar. With so many uses, benefits, and recipes, it’s no wonder why the whole country will be celebrating National Vinegar Day on November 1. If someone asked you what vinegar is, could you explain it? This typically falls under the umbrella of information we file away in the “things we say we know but hope no one will ask about” folder, along with how pineapples grow and how magnets work. In short, vinegar is made by fermenting something passed the point of an alcoholic drink until it’s acidic. This is why we have different kinds of vinegars, just as we have different kinds of wines and liqueurs. So get ready to try something new and learn more about this complex concoction we rarely think twice about.
